ANTIGREEPER FOR RAILS.

Specification of Letters Patent.

Patented Feb. 1, 1916,

Application filed November A13, .1915. Serial No. 61,240.

To all whom 'it may concern:

Be it known that I, Louis J. RIEGLER, a citizen of the United States, and resident of Ben Avon, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Anticreepers for Rails; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to anti-Creepers for rails, such as devices for preventing the creeping of railroad rails along the ties, and such devices are also known as rail anchors and creep checks.

Anticreepers as hereinbefore constructed, and used, are embraced in two general types, one of which is intended to grip the rail suiiiciently to prevent creeping immediately upon vbeing applied, and the other is intended that the creeping of the rail further tightens the grip and thus eventually prevents the creeping.

The object of my invention is to provide an anti-Creeper, which will have the advantages of both these types and to form a cheap, simple and efficient device of such character, which will be easy to manufacture, can be readily applied to the rails, and will maintain an eifective grip upon the rails in order to prevent the creeping` of the same.

To these ends my invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set i'orth and described and particularly pointed out in the claims.

T o enable others skilled in the art vto which my invention appertains to construct and use my improved anti-creeper for rails, I will describe the same more fully, referring to the accompanying drawing, in which- Figure 1 shows a cross section of the ordi nary railroad rail having my improved anticreeper applied thereto and in position for clamping on such rail. Fig. 2 is a. likeview showing the wedge applied to the anticreeper for clamping the same to the rail. Fig. 3 is a side elevation of the wedge employed. Fig. L is an elevation of the rail showing the anticreeper in position with respect to the rail and tie. Fig. 5 is a, top view of the anti-Creeper. Fig' 1s a view of the filler block employed. Figs. 7 and S are views of other forms of the anti-Creeper.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

As illustrated in the drawing A represents the usual railroad rail having the head a, web Z and bottom iiange c. The yoke for iitting around the rail flange c is shown at 1 and is preferably formed in one piece and by rolling, casting or forging, so as to provide for the body portion 2, and jaws 3 and 4 thereon. The jaw 3 is formed to iit closely overthe edge oi' one side of the rail flange c and the jaw l is formed longer and with a greater opening between the same and the body portion 2 so as to allow the jaw 3 to slip over its flange edge when the jaw d is moved up against the opposite flange. The central portion 5 of the body 2 of the yoke l ismade thinner than at the ends of the same where they are connected to the jaws 3 and l, in order that it may bend freely at such portion when the yoke 1 is tightened on the rail flange c, as hereinafter described.

When the yoke l is being applied to the rail flange c adjacent to the tie B supporting such rail A. the jaw 1 is placed over one edge ci' said flange, and then the jaw 3 is placed 1n pos'. on over and against the opposite rail flange, so that while the yoke is being held in this position, a'iiller block 6 formed by rolling, pressing or casting, is slid into place under the jaw et and against the rail flange, which will. place the body portion 2 of such yoke in close proximity to the under face of such fla-nge. A. wedge 7 formed by pressing or forging and having a tapered portion 8 and a depending portion or lug 9 is adapted to have its depending portionplaced against the tie B and its tapered portion inserted between the rail iiange c and the central portion 5 on the yoke 1 by pressure applied to said yoke, so that when such wedge is forced into position said central portion will bend downward or outward, and the yoke and jaws 3 and l will tend to take the position as shown in Fig. 2, thereby enabling the said jaws to be drawn down on and tight against the outer edges and upper surfaces of the rail flange.

. 1n Fig. 8 is shown another form of my improved anti-creeper, in which the ller block 6 is dispensed with and a larger wedge 7 such as is shown, is used so that -in this Figs. 2, 3 and 4:.

In Fig. 7, another form of the wedge 7 1s shown in which the yoke engaging side of the same is in the form of a segment of a g, circle, as at 74, and the jaws 3 in this case "1. arethe same as those shown in Fig. 8, withoutl a. filler block. 'various other modifications and changes the design and construction of my imovod "antirreeper may be resorted to veiition or sacricing any of its advantages.

It ,will thus be seen that the yoke, as hereiiib'efore' described is designed to cause the body of the same to be stressed in direct tension, rather than inV bending, when the 'wedgeis forced in to cause the jaws of the 'yoke to gripthe rail flanges. In one piece yso yekes as heretobefore constructed, the pressure developed by forcing in the wedge,

` causes bending stresses in the body of the yoke. The pressure therefore developed between the jaws of these former yokes and the rail danges, between the wedge and the bottom of the rail and between the Wedge and yoke is limited to the strength of the body of the yoke acting as a beam, thus requirin a yoke made of a material having a high e astio limit to develop sufficient pressure between the jaws and rail flanges for firmly gripping the rail. With the yoke of my improved device the thin portion at the center allows the metal at such point to bend freely and act as a flexible connection, thus causing the jaws to draw inwardly toward the flanges of the r'ail, as the wedge is forced in and setting up tensile stresses only in the body of the yoke. The advantage of'this is obvious, as a given amount of metal oders considerably vmore resistance in direct ten- A sion'fftlian in bending.

Inthe one piece yokes heretofore con-4 'in structed, the gripping pressure between the Aeo v thej'pressure between'the jaws and -the rail jaws and the rail flanges is purely vertical, and @such pressure sets up great bending stresses in the haunehes of the jaws, and is due to the long lever arm of `one of the jaws which is necessary to pass the jaws over the rail flanges. ln my improved anti-Creeper,

flancs is horizontal and the lever arm is reduce l, thus permitting greater pressure for gripping the rail flanges.

is principle may also be found effective for the form of wedge shown 1nl tho'utv departing from the spirit of the inv as in the latter, the pressure of the jaws on the rail flanges is equal to one-half that developed by the wedge when forced in, while in my improved construction it is equal to the pressure developed by the wedge when forced in, and multiplied a number oftimes, depending upon the. ratio of the width of the rail flange to the thickness of the wedge.
